AIM:To investigate the effect of suramin concentration changes on trabeculectomy in rabbit, and to provide treatment strategies for glaucoma on the basis of experiment.
METHODS:Thirty-two albino rabbits were randomly divided into four groups, including standard control group, experimental group Ⅰ, experimental group II, and experimental group Ⅲ. Each eye was performed standard trabeculectomy. During surgery, standard control group was given a piece of cotton with 0. 3mg/mL mitomycin C ( MMC ) for 2min, and the other three groups were given a piece of cotton with 0. 3, 0. 4, and 0.5mg/mL suramin respectively for 2min. The filtering blebs and intraocular pressure ( IOP ) were observed at the 3, 7, 15, and 30d after surgery. Some conjunctiral specimen were observed with hitochemicall ( HE staining) and immunohistochemicall methods.
RESULTS:At postoperative 7, 15, and 30d, the changes of the IOP, functional filtering blebs, and the number of positive cell nuclear in experimental group II and experimental group Ⅲ were significantly different compared with those in standard control group and experimental group Ⅰ (all P<0. 05), and the differences between experimental group Ⅰ and standard control group were not significant (P>0. 05). The changes of the IOP and the number of positive cell nuclear in experimental group Ⅲ were significantly different compared with those in experimental group II (P<0. 05), whereas the differences in functional filtering blebs between experimental group Ⅲ and experimental groupII were not significant (P>0. 05). The status of filtering channel in experimental groupII and experimental group
Ⅲ were better than those in experimental group Ⅰ and standard control group.
CONCLUSION: The concentration of suramin has a significantly influence on its effect. When the concentration is 0. 3mg/mL, the antiproliferative effect of suramin is no more than that of MMC. The effect of 0. 4, 0.5mg/mL suramin is better than MMC. 0. 5mg/mL suramin has a better effect on controlling IOP and suppressing the growth of fibroblasts than 0. 4mg/mL suramin.

The growth and pigment production of 47 strains on casein medium were studied comparatively.T4 and Neurospora crassa AS 3.1602 were selected for their capacity of producing melanin on five different culture media. Melanin produced by T4 was investigated, and T4 was identified as Proteus mirabilis primarily.

BACKGROUND:Lumbar spinal stenosis can severely affect the activities and functions of the lower limbs, and even cause paralysis. OBJECTIVE:To evaluate the clinical effect of intervertebral bone graft with internal fixation for the treatment of lumbar spinal stenosis. METHODS:The lumbar spinal stenosis patients treated with posterior decompression and intervertebral bone graft with internal fixation were fol owed-up. The effect of intervertebral bone graft with internal fixation for the treatment of lumbar spinal stenosis was evaluated through assessing the clinical symptoms and improvement of signs, recovery of neurological function, as wel as intervertebral bone graft and fusion and the occurrence of complications. The effects of posterior decompression and intervertebral bone graft with internal fixation and simple decompression for the treatment of lumbar spinal stenosis were compared, in order to further determine the treatment of intervertebral bone graft with internal fixation. RESUTLS AND CONCLUSION:The fol ow-up results of the lumbar spinal stenosis patients treated with posterior decompression and intervertebral bone graft with internal fixation showed that the symptoms of low back pain, partial limb sensory disturbances and intermittent claudication were improved significantly;the neurological recovery score could be up to 90%or above. Radiographic examination showed good intervertebral bone graft and fusion with less complication of nerves, blood vessels and dural injury. Comparative study showed that the excel ent and good rate of posterior decompression and intervertebral bone graft with internal fixation can reach to 95.2%, while the excel ent and good rate of simple decompression was 23.8%, indicating that the effect of posterior decompression and intervertebral bone graft with internal fixation was significantly better than that of simple decompression.

BACKGROUND: Selective posterior rhizotomy has been extensively acknowledged as an effective method of relieving lower limb spasticity in cerebral palsy. However, the postoperative complications such as reduced muscle strength and imbalance of the spine are of concern among surgeons and therapists. The combination of limited selective posterior rhizotomy (LSPR) with adductor tenotomy can decrease these complications without compromising the treatment effects.OBJECTIVE: To investigate the effects of combination therapy of LSPR with adductor tenotomy on lower limb spasticity, gait and movement of the patients.DESIGN: A self-controlled trial and observational follow-up taking children with cerebral palsy as the subjects.SETTING: Orthopedic Department of First Hospital Affiliated to Dalian Medical University.PARTICIPANTS: Thirty children patients with cerebral palsy treated in the Orthopedics Department of the First Affiliated Hospital of Jilin University from January 2001 to December 2002 were recruited in this trial. They presented scissors gait, flexed knee and tiptoeing of different degree. There were 18 cases of brisk tendon reflex and ankle clonus, and 15 cases of positive Babinski' s sign. All the patients had no immobile soft tissue contracture and could either accomplish walking and crouching independently or walk with arms on assistant devices.INTERVENTIONS: The patients received LSPR of L5 and S1 dorsal roots together with bilateral adductor tenotomy. Muscle tone and strength, knee and Achilles tendon reflexes, ankle clonus and pathologic signs were recorded before and after operation. X-ray examination on lumbar spine and pelvic was also taken for detection of deformity. The patients' movements were assessed according to their standing and walking postures, standing and crouching movements before operation and on follow-up. During follow-up all the mentioned indices were recorded by reference to the original case history, hospital reexamination and correspondence with the patients.MAIN OUTCOME MEASURES: The amelioration in lower limb spasticity and grading of lower limb()movements.RESULTS: During the follow-up for six months to three years(the mean of 11 months), the patients' lower limb spasticity was decreased by 2. 5 grades. The gait was also improved with disappeared scissors gait and tiptoeing, knee flexion was improved and the patients could walk with heels on the ground. All ankle clonus and pathologic reflexes disappeared. The brisk knee reflex in 12 patients became sluggish after operation. There was no decrease in lower limb strength or permanent hypesthesia. X-ray examination of lumbar spine and pelvic showed no deformity in 9 patients after over 2-year follow-up. The upper limb spasticity, salivation and aphasia in 8 patients were also ameliorated. The grading for postoperative standing, walking and crouching-standing alternation[(4.25±0.91), (3.92±0.65) and(4.02±0.74)] wasimproved(t=2.04-2.98, P ＜0.05-0.01).CONCLUSION: The combination of LSPR with adductor tenotomy can effectively ameliorate lower limb spasticity and movement with decreased operative damage.

Neoplastic stem cells (NSCs)are the source of tumor occurrence and development,and its special microenvironment is involved in tumor drug resistance,recurrence and metastasis by regulating NSCs or changing itself. Eradicating NSCs and interfering the special microenvironment may be the new therapeutic strategies for cancer.

The treatment plan of facial neuritis in Evidence-based Guidelines of Clinical Practice in Acupuncture and Moxibustion (2011 edition) is discussed, and case information of facial neuritis during the recent five years in department of acupuncture and moxibustion, PLA General Hospital, is retrospectively analyzed. In accordance with anatomy of the facial nerve to form the acupuncture prescription, the detailed diagnosis and treatment method for facial neuritis are introduced. The advantages of the diagnosis and treatment method for facial neuritis are summarized, hoping to establish a more comprehensive, standardized and unified treatment plan.
